Introduction

Confined space definition:Is large enough that an

employee can enter and perform assigned work

Has limited or restricted means for entry or exit

Is not designed for continuous employee occupancy

IntroductionRegulatory Requirements

OSHA- employee safety- permit confined spaces- 29 CFR 1910.146

The employer must assess the workplace to determine if hazards are present that necessitate the use of PPE

Permit Space Hazards

• Hazardous atmosphere (too little or too much oxygen, flammable or toxic air)

• Engulfment• Danger from unexpected movement of

machinery• Electrocution• Heat stress• Becoming wedged into a narrow space and

suffocating

Reducing Risks of HazardsDevelop and use a written Standard Operating

Procedures for confined space rescue teamConduct air monitoring and other tests to

identify and evaluate hazards in each permit space

Ventilate, eliminate, or control the space’s atmospheric hazards before entry into the space

Lock-Out/Tag-Out ensure and place our Lock-out/ Tag out kit on were needed.

Preparation of Permit Space

Post signs and put up barriers to protect entrants from traffic and pedestrians

Blind or disconnect and cap all input lines so that no hazardous materials can enter the space

Empty space of any materials that may be hazardous

Verify breathing safety by air testing

Safety Procedures

Authorized entrants can enter a permit space only after it’s been tested and found safe for entry

The assigned entrant has to know what equipment to use- and how to use it

Once prepared, you want to get in and do the assigned task as quickly and efficiently as possible

Alert the attendant immediately if you recognize a sign or symptom of exposure to a dangerous situation

NFPA

7.1.4 A confined space rescue team shall be made up of a minimum of six individuals for organizations operating at the technician level, and a minimum of four individuals for organizations operating at the operations level. 

LEVELS OF RESUCE CERTS.

AWARNESSOPERATIONSTECHNICIAN

We operate at the Technician Level

ASSESMENT OF THE SCENE

(1)      Hazards such as engulfment potential, environmental hazards (e.g., chemical, atmospheric, temperature), harmful forms of energy (e.g., electrical, mechanical, movement due to gravity, hydraulic), configuration hazards (e.g., diverging walls, entrapment, obstructions, trip/fall hazards), and so forth 

(2)      Risk/benefit analysis (body recovery versus rescue)  (3)      Available/necessary additional resources  (4)      Establishment of control zones  (5)      Magnitude of the hazard and isolation procedures  (6)      Effectiveness of the non-entry or qualifying entry-type

rescue  (7)      Overall safety of rescue operations  (8)      Level of rescue response (appropriate for the type of

rescue being attempted)  (9)      Current and projected status of the planned response  (10)      Personnel accountability

Site Safety Plan

                                   A site safety plan can also provide useful

information for consideration during size-up and should include the following: 

(1)      Rescue team notification  (2)      Acceptable entry conditions for

rescue  (3)      Hazard identification  (4)      Risk assessment of hazards  (5)      Site map                   

Site Safety Plan

6)      Hazard abatement (including control zones, ventilation, and lock-out/tag-out procedures) 

(7)      Use of buddy system (where applicable) 

(8)      Communications (e.g., site, rescue attendant to rescue entrant) 

(9)      Command post (10)      Incident management

organizational chart 

Site Safety Plan

(11)      Standard operating guidelines 

(12)      Safe work practices (13)      Medical assistance (14)      Pre-entry safety briefings (15)      Pre- and post-entry physicals

(if indicated)
